they usually come before you ask someone out
not really, isn't that what dating is for?
they can be scary.
deoends on the person
Dating, to me, is a way to get to know people better. Some dates go well, others don't. Either way, you learn more about the other person. As you learn more about a person, you can develop feelings for them. I think you have to have some sort of attraction to have the desire to want to go on a date with them, but no prior feelings are necessary.
If you aren't in it you aren't in it. You shouldn't go on a date because people tell yo she's interested, if anything that may only just lead her on. It's important to date on your terms, but a leap of faith has worked for people in the past. Maybe it doesn't have to have the 'date' title slapped onto it? Maybe try something casual and mellow, if anything.
Maybe it blossoms into love, maybe you become friends with benefits, maybe nothing happens and you can just go on with your lives.
I wouldn't ask someone out just because they are interested though, I wouldn't want it to feel like a pity date or anything.
Right on, worst case scenario you just go on doing your thing! And thank you for the compliment! Hope all goes well in the future.
Either way.. It can start as casual dates first..
